Title: Nonstandard signal detecting circuit
Inventor: OKI HIDEAKI
IPC: H04N9/77
Filed: 1988-06-29
Abstract: PURPOSE:To increase the accuracy of nonstandard signal detection and to prevent a malfunction by detecting the discontinuous point of a burst signal in any phase difference when the burst signal becomes discontinuous. CONSTITUTION:By setting the phase difference between a clock signal inputted from a phase shifting means 116 to a phase comparing means 117 and the input burst signal from a terminal 102 at 90 deg., when an APC circuit consisting of a phase comparing circuit 103, a low pass filter 104 and a voltage controlled type oscillating circuit 105 is phase-locked, the output signal of a filter means 118 is made into a + maximum value or a - maximum value. Presently, if the signal is temporarily set at the + maximum voltage, when the phase of the inputted burst signal has the phase difference at 180 deg. with respect to the phase at the time of the phase locking, the output signal of the filter means 118 is set at the - maximum value. Thus, in a comparing means 110, the nonstandard signal can be detected even for the input burst signal having the phase difference of 180 deg., and the erroneous detection can be eliminated.

Title: Magnetic head holding mechanism
Inventor: HANAGATA SHIZUO
IPC: G11B21/20
Filed: 1985-07-19
Abstract: PURPOSE:To protect a head from damaging by so constituting the titled mechanism that the magnetic head on the side of a movable carrier rises to a considerable height when loading/unloading a medium and another head on the side of another carrier is lowered lower than a spindle plane and detaches from the medium or its protection jacket. CONSTITUTION:The supporting part 24 of a plate spring 11 to its carrier 14 is bent by a small angle. Because of the said angle theta, the magnetic head 13 is lowered lower than the plane 15 of the spindle to the direction of carrier 4. Therefore, during the loading/unloading of the medium, the medium 16 does not contact the head 13. Also, the magnetic head 13 can be lowered by such sufficient length that the protection jacket does not contact the head 13 for the irregular bendings of the medium 16. For purposes of writing and reading, the medium 16 is mounted, and the magnetic head 13 is allowed to contact with it, at this time a pressing bar 12 moves upward by the inclined plane 9 of a rod 8, and is then positioned on the flat plane 10 to stop the movement.

Abstract: PURPOSE:To facilitate the attachment of a hook to a duct and the removal of the hook from the duct by equipping this device with a hook, which elastically hooks on the margin of the opening of a plug-in hole, and a release member, which releases the hooking of this hook. CONSTITUTION:When a plug-in head 15 is inserted into the plug-in hole 3 of a duct 1 and a branching device is pushed up, the tilt part 28 of a hook 25 abuts on the margin of the plug-in hole 3, whereby it receives force, and the hook 25 shifts inward, resisting the elasticity of a spring. Furthermore, when the branching device 2 goes up, the abutment between the tilt part 28 of the hook 25 and the plug-in hole 3 is released, and the spring returns, and the groove 29 of the hook 25 gets in the margin of the plug-in hole 3 and is locked elastically. To remove the branching device 2, the hook 25 shifts inward by pushing the releasing member 27, whereby the lock condition is released. Hereby, the attachment of the hook 25 to the duct 1 and the removal of the hook 25 from the duct 1 can be performed easily.

Abstract: PURPOSE:To make it possible even for a layman on electricity to discover the abnormality of a transformer by operating an alarm device and to improve safety by winding a resistance coil, a resistance value of which alters due to a temperature change by operation, on a general-purpose transformer circuit only by required number. CONSTITUTION:A resistance coil 4, a resistance value of which varies due to a temperature change by operation, is wound on a general-purpose transformer circuit composed of a primary coil 1 and a secondary coil 2 and a core 3 only by required number. The resistance coil 4 has electromotive force, but electromotive force is lowered when the load currents of the secondary coil 2 are increased and the magnetic flux of the core 3 is saturated, and an ammeter 6 cannot be swung sufficiently through a resistor 5 for adjusting currents. When the temperature of a transformer is elevated by the change of peripheral environment even at the time of enough electromotive force, the resistance of the resistance coil is augmented, and the ammeter 6 cannot be swung sufficiently. The alarm actuating contact 7 of the ammeter 6 is operated even in either case, and the transformer is protected from the saturation of magnetic flux, a temperature rise, etc., by an alarm device, a signal, etc.

Title: Facsimile broadcast receiver
Inventor: SUGA NOBUAKI
IPC: H04N7/081
Filed: 1987-06-26
Abstract: PURPOSE:To perform stable separation without being affected by noise by integrating the part of an identification signal in response to a gate signal, comparing its integral value with a preset reference value, and discriminating between an image signal and a control signal. CONSTITUTION:A signal separating circuit 5 separates a facsimile signal from a demodulating circuit 4 into an image signal (luminance signal and color difference signal) and the control signal. Then the part corresponding to the identification part is integrated in response to the gate signal and its integral value is compared with the preset reference value to discriminate between the image signal and control signal. Therefore, even if a noise enters the part of the identification signal, the integral value is hardly affected by the noise. Consequently, a receiver is obtained which is immune to noise and performs stable signal separation.
